Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Long- and short-term stability of plasticized poly(lactic
Addition of plasticizers (regardless of plasticizer type) to the PLA, even at lower loading levels (5 wt%), decreased the yield strength and modulus of PLA. It is known that plasticizers result in a decrease in the intermolecular forces between the polymer chains, which lowers the polymer chain cohesion . Yield strength and the modulus of PLA
Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887...
Superplasticizer | Concrete plasticizer for better concrete
Superplasticizers are used in conventional manufacturing processes as well as in highly-flowable and self-compacting concrete (SCC). ALPHALITH admixtures have proven to be effective in the production of ready-mixed and construction site concrete with the highest requirements, such as high-strength concrete up to C100/115.
Plasticizers in Paint & Coatings: Uses, Types and Selection
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
- Which superplasticizer admixture is better?
- Based on the findings, out of three superplasticizers, PC—based admixture showed a better improvement in strength aspects compared to other mix. Compressive strength of UHPC (a) SNF admixture (b) SMF admixture (c) PC admixture
- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
- Which superplasticizer has a negative zeta potential?
- Generally, superplasticizers with higher molecular weight adsorbed less resulting in negative zeta potential and vice versa . SNF-based super plasticizer possesses high fluidity due to reduced monomer and increased molecular weight.
- What is the maximum tensile strength of a superplasticizer?
- The maximum split tensile strength at 28 days of testing for all cases was found to be 29.09 MPa—SNF based, 30.72 MPa—SMF based, and 31.23 MPa—PC-based admixture, respectively, at 1.5% of dosage (Fig. 6). Therefore, the effect of superplasticizers mainly influences the workability of concrete rather mechanical properties.
- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes. They achieve a reduction in water content without loss of workability.
- Are PC-based admixtures more prominent than sulphonated superplasticizers?
- Based on the observation, it is recommended that PC-based admixtures are more prominent than sulphonated superplasticizers in terms of water reduction, workability, and strength aspects. Discover the latest articles, news and stories from top researchers in related subjects.
